General Description
HVAC SYSTEM (HEATER, VENTILATOR AND A/C)
C: CAUTION
1. HFC-134A A/C SYSTEM
•The cooling system components for the HFC-
134a system such as the refrigerant and compres-
sor oil are different from the conventional CFC-12
system components and they are incompatible with
each other.
•Vehicles with the HFC-134a system can be iden-
tified by the label (A) attached to the vehicle.
Before maintenance, check which A/C system is in-
stalled to the vehicle.
2. COMPRESSOR OIL
•HFC-134a compressor oil has no compatibility
with that of CFC-12 system.
•Use only Denso Oil 8, the manufacturer-autho-
rized compressor oil for the HFC-134a system.
•Do not mix multiple compressor oils.
If CFC-12 compressor oil is used in the HFC-134a
A/C system, the compressor may become stuck
due to poor lubrication, or the refrigerant may leak
due to swelling of rubber parts.
On the other hand, if HFC-134a compressor oil is
used in a CFC-12 A/C system, the durability of the
A/C system will be lowered.
•HFC-134a compressor oil is very hygroscopic.
When replacing or installing/removing A/C parts,
immediately isolate the oil from atmosphere using a
plug or tape. In order to avoid moisture, store the oil
in a container with its cap tightly closed.
3. REFRIGERANT
•CFC-12 refrigerant cannot be used in a HFC-
134a A/C system. HFC-134a refrigerant, also can-
not be used in a CFC-12 A/C system.
•If an incorrect or no refrigerant is used, it will re-
sult in poor lubrication and the compressor itself
may be damaged.
4. HANDLING OF REFRIGERANT
•The refrigerant boils at approx. –30°C (22°F).
When handling it, be sure to wear protective gog-
gles and protective gloves. Direct contact of the re-
frigerant with skin may cause frostbite.
If the refrigerant gets into your eye, avoid rubbing
your eyes with your hands. Wash your eye with
plenty of water, and receive medical treatment from
an eye doctor.
•Do not heat a service can. If a service can is di-
rectly heated, or put into boiling water, the inside
pressure will become extremely high. This may
cause the can to explode. If a service can must be
warmed up, use warm water of 40°C (104°F) or less.
•Do not drop or subject a service can to impacts.
(Observe the precautions and operation procedure
described on the refrigerant can.)
•When the engine is running, do not open the
high-pressure valve of the manifold gauge. High-
pressure gas can back-flow resulting in an explo-
sion of the can.
•Provide good ventilation and do not work in a
closed area.
•In order to prevent global warming, avoid releas-
ing HFC-134a into the atmosphere. Using a refrig-
erant recovery system, discharge and recycle the
gas.

Refrigerant Recovery Procedure
HVAC SYSTEM (HEATER, VENTILATOR AND A/C)
3. Refrigerant Recovery Proce-
dure
A: PROCEDURE
CAUTION:
•During operation, be sure to wear protective
goggles and protective gloves.
•Connect the refrigerant recovery system with
the manifold gauge set to discharge the refrig-
erant from the A/C system and recycle the gas.
•When recycling the discharged refrigerant,
keep service cans on hand. Because the recov-
ery rate with the recovery system is approx.
90%, service cans are necessary to charge the
refrigerant.
•Follow the detailed operation procedure de-
scribed in the operation manual attached to the
refrigerant recovery system.
1) Perform the compressor oil return operation.
2) Stop the engine.
3) Make sure the valves on low-/high-pressure
sides of manifold gauge set are fully closed.
4) Install the low-/high-pressure hoses to the ser-
vice ports on the low-/high-pressure sides of the
vehicle respectively.
5) Connect the center hose to the refrigerant recov-
ery system.
6) Follow the operation manual to activate the re-
frigerant recovery system.

Refrigerant Charging Procedure
HVAC SYSTEM (HEATER, VENTILATOR AND A/C)
4. Refrigerant Charging Proce-
dure
A: PROCEDURE
CAUTION:
•During operation, be sure to wear protective
goggles and protective gloves.
•Before charging the refrigerant, evacuate the
system to remove small amounts of moisture
remaining in the system.
The moisture in the system can be completely
evacuated only under the minimum vacuum
level. The minimum vacuum level affects the
temperature in the system.
•The list below shows the vacuum values nec-
essary to boil water at various temperatures. In
addition, the vacuum levels indicated on the
gauge are approx. 3.3 kPa (25 mmHg, 0.98 inHg)
lower than those measured at 304.8 m (1,000 ft)
above sea level.
1) Close the valves on low-/high-pressure sides of
the manifold gauge.
2) Install the low-/high-pressure hoses to the corre-
sponding service ports on the vehicle.
3) Connect the center hose of the manifold gauge
set with the vacuum pump.
4) Carefully open the valves on the low-/high-pres-
sure sides to activate the vacuum pump.
5) After the low-pressure gauge reaches 100.0 kPa
(750 mmHg, 29.5 inHg) or higher, evacuate the
system for approx. 15 minutes. (Continue evacua-
tion).
6) After 15 minutes of evacuation, if the reading
shows 100.0 kPa (750 mmHg, 29.5 inHg) or higher,
close the valves on the both sides to stop the vac-
uum pump.

Refrigerant Leak Check
HVAC SYSTEM (HEATER, VENTILATOR AND A/C)
5. Refrigerant Leak Check
A: INSPECTION
1) At engine speed below 1500rpm, operate the A/
C system for approx. 10 minutes, and confirm that
the high-side pressure shows at least 690 kPa
(7.03 kg/cm2, 100 psi). Then stop the engine to
start the leak test.
2) Starting from the connection between high-pres-
sure pipe and evaporator, check the system for
leaks along the high-pressure side through the
compressor. The following items must be checked
thoroughly.
3) Check the joint and seam between pressure
switch (dual switch) and high-pressure pipe.
4) Check the connections between condenser and
pipes, and welded joints on the condenser.
The leak tester may detect the oil on the condenser
fins as a leak.
5) Check the joint between compressor and hoses.
6) Check the machined area of the compressor and
other joints on the compressor.
7) Check the compressor shaft seal at the area
near the center of compressor clutch pulley.
Some shaft seals show a slight amount of leakage,
about 3 g (0.1 oz) per year. This is not a problem.
8) Starting from the connection between low-pres-
sure pipe and evaporator, check the system for
leakage along the low-pressure side through the
compressor. The following items must be checked
thoroughly.
•Connection between 2 parts
•Connection between pipe and plate
•Connection between pipes
9) Visually check the rubber area of the flexible
hose for cracks.
Check the entire length of the flexible hose, espe-
cially the connection with the metal hose end.
CAUTION:
Carefully check the external surface of hoses
and tubes at approx. 25 mm (0.98 in) per sec-
ond.
10) Disconnect the drain hose from the heater
case, and check the hose end for at least 10 sec-
onds.
After the test is finished, reconnect the drain hose.
11) Turn the ignition key to the ON position, and
run the blower at high speed for approx. 1 minute.
Stop the blower to check the ventilation grill on the
instrument panel. While moving the tester closer to
the grill, run the blower for 1 or 2 seconds, then stop
it. Check the grill at that point for at least 10 sec-
onds.
12) Check the valve in the service port.
13) Visually check the rubber seal in the service
port cap.
